Use gcc 3.4.6 for m68k-amigaos-toolchain

This changes to using the 3.4 series gcc with patches from
github:cahirwpz/m68k-amigaos-toolchain and some other modifications to
make it compile.

clib2 is currently failing to build with this compiler with the
following errors:

+
+This document is supposed to be an addendum to the baseline @samp{GCC}
+documentation.
+Note that given email addresses and urls might be obsolete!
+
+It focuses on the features that are visible by users and are important
+to them. It is not supposed to document the internals of the AmigaOS
+port of @samp{GCC}.
+
+It describes features implemented in the @samp{Geek Gadgets GCC} port.

+@end format
+
+This document focuses on @samp{GCC}. It does not describe the
+AmigaOS-only features of other @samp{GNU} packages, such as
+@samp{binutils}, unless they are very closely connected to @samp{GCC}.
+
+This means, that, unless stated otherwise, when we talk about the
+``compiler'', we mean the @file{gcc}, @file{cpp} and @file{cc1}
+executables, i.e., the executables that convert @samp{C} source code
+to assembly source code. The assembler and linker are generally beyond
+the scope of this document.
+
+The primary source of information used to create this document was the
+@samp{GCC} source code. Some parts of this document are based on:

+
+@cindex IXEmul
+By default, the executables created with @samp{GCC} require
+@samp{ixemul.library} to run. This has its advantages (easy porting of
+@samp{UN*X} programs, resource tracking, debugging, profiling, etc)
+and disadvantages (@samp{UN*X}-style pathnames, large shared library,
+etc).
+
+@cindex LibNIX
+If @samp{-noixemul} is specified on the @samp{GCC} command line, the
+executable created will not require @samp{ixemul.library} --- it will
+use the static linker library @samp{LibNIX} instead. This library is
+very Amiga-like and @samp{SAS/C}-like, so it is convenient for the
+AmigaOS-specific development.
+
+@quotation
+@emph{Note}: There is no great mystery about the @samp{-noixemul}
+option. It has absolutely no effect on the code generated by the

+The @samp{-fbaserel} option will make @samp{GCC} generate code that

+cannot be used for large programs, like @samp{GCC} itself.
+
+@quotation
+@emph{Note}: For a base-relative executable, @samp{-fbaserel} needs to

+require special startup code and special versions of linker libraries.
+Since not all linker libraries are available in both plain and base
+relative versions, the usefulness of this option is limited. It is

+where the stack is extended automagically whenever needed.
+
+Unfortunately, the AmigaOS provides tasks with a static, fixed size
+stack.
+
+However, if a program is compiled with @samp{-mstackcheck}, it will
+check if there is enough stack available before performing any
+stack-hungry operations. If there is a danger of stack overflow, the
+program will abort and the user will be notified.
+
+Needless to say, stack checking increases the executable size and the

+@section -mregparm
+@cindex -mregparm
+@cindex Pass function arguments in registers
+
+On the @samp{m68k} architecture, @samp{GCC} passes function arguments
+on the stack by default.
+
+@samp{-mregparm} allows for passing arguments in registers. This can
+be slightly faster than the standard method of passing arguments on
+the stack.
+
+The full syntax of this option is:
+
+@format
+-mregparm[=<value>]
+@end format
+
+@samp{value} should be an integer ranging from 1 to 4. If no
+@samp{value} is provided, 2 will be used.
+
+Four types of function arguments are recognized:
+
+@table @samp
+@item Integer
+Integer numbers (this includes enumerations, small structures and
+@samp{bool} in @samp{C++}, but excludes @samp{long long}, which is too
+large). They are passed in data registers, starting from @samp{d0}.
+
+@item Pointer
+Pointers to objects or functions (this includes @samp{C++} references
+and the implicit @samp{this} argument). They are passed in address
+registers, starting from @samp{a0}.
+
+@item Float
+Floating point numbers. If the floating point code generation is
+enabled, they are passed in floating point registers, starting from
+@samp{fp0}. Otherwise, they are handled like the next type.
+
+@item Other
+All the other types of arguments, like large structures, pointers to
+class methods in @samp{C++}, etc. They are always passed on the stack.
+@end table
+
+The value given for @samp{-mregparm} indicates how many arguments of
+each of the above first three types should be passed in registers.
+
+Example: @samp{GCC} is invoked with @samp{-mregparm} (without any
+value, so 2 will be used) to compile a source containing the function:
+
+@example
+void fun(int a, char *str, char b, int c);
+@end example
+
+@samp{a} and @samp{b} will be passed in @samp{d0} and @samp{d1},
+respectively, @samp{str} will be passed in @samp{a0}, and @samp{c}
+will be passed on the stack.
+
+@quotation
+@emph{Note}: To use this option properly, it is very important that
+all sources are fully prototyped. There may be very serious problems
+if they are not, since @samp{GCC} will have to ``guess'' where to put
+arguments, potentially making a wrong decission. Example:
+
+@example
+[in file1.c]
+void f(void)
+@{
+   g(0); /* Call to a function with no prototype.  The argument
+            will be put in d0, since it is an integer.  */
+@}
+
+[in file2.c]
+void g(char *a) /* The argument is expected in a0, since it is
+                   a pointer.  */
+@{
+@}
+@end example
+
+@samp{-Wimplicit -Wstrict-prototypes} should be used to ensure that
+there are no prototypes missing.
+
+In case of @samp{stdargs} functions, such as @samp{printf}, all
+arguments are passed on the stack.
+
+As of this writing, @samp{-mregparm} is supported by neither
+@samp{IXEmul} nor @samp{LibNIX}, so its usefulness is very limited.
+
+This option was first made available in the @samp{GCC} 2.7.2.1,
+@samp{Geek Gadgets} snapshot @samp{961012}.

+@cindex Put object in chip memory
+
+Amiga hardware requires some data to be located in @samp{chip} memory.
+
+Typically, if an initialized buffer is required (containing a picture
+bitmap, for example), a plain, statically initialized buffer is used,
+and the data is copied into a dynamically allocated @samp{MEMF_CHIP}
+buffer.
+
+This is not necessary with the @samp{chip} attribute. If this
+attribute is specified for an initialized, static variable, it will be
+allocated in @samp{chip} memory automagically by the AmigaOS.
+
+A small example:
+
+@example
+UWORD __attribute__((chip)) bitmap1[] = @{ ... @};
+@end example
+
+@quotation
+@emph{Note}: For compatibility with other AmigaOS @samp{C} compilers,
+a preprocessor symbol @samp{__chip} is available, which expands to
+@code{__attribute__((chip))} (@pxref{Keyword macros}).
+
+All the @samp{chip} attribute does is specifying that data should go
+to a section called @samp{.datachip}. Therefore, the standard
+@samp{GCC} feature @code{__attribute__((section(".datachip")))} can be
+used instead.
+
+This attribute was first made available in the @samp{GCC} 2.7.2.1,
+@samp{Geek Gadgets} snapshot @samp{970328}.
+
+For proper operation, this attribute requires a special version of the

+function which references global data.
+
+This is only safe as long as all function calls are performed from
+within your own code. Things become ``tricky'' if callback functions,
+like the AmigaOS hooks, interrupt handlers etc. are used. If global
+data is referenced in such functions, @samp{a4} has to be set
+properly.
+
+This is exactly what the @samp{saveds} attribute does: it initializes
+@samp{a4} in the function prologue, and restores it to its original
+value in the function epilogue.

+arguments are passed. It makes @samp{GCC} pass arguments on stack for
+the function for which it was used, regardless of whether the global
+@samp{-mregparm} option was used or not (@pxref{-mregparm}).

+@samp{GCC} has several options to choose the CPU model that the code

+which options have been specified on the command line:
+
+@table @samp

+@emph{Note}: The symbols beginning with @samp{mc} are available in
+three groups: plain (as specified above), with two leading
+underscores, and with two leading and two tailing underscores. The
+plain ones are not available when compiling with the @samp{-ansi}
+option. The ``underscored'' ones were first made available in the

+
+@samp{mc68000} is defined regardless of which @samp{-m680x0} options

+
+In addition to the above, a preprocessor symbol @samp{ixemul}

+@section ``Keyword'' macros
+@cindex Keyword macros
+@cindex Compatibility with other compilers
+
+Most AmigaOS-specific @samp{C} compilers have special ``custom
+keywords'', which make the AmigaOS-specific development easier.
+Unfortunately, the idea of ``custom keywords'' is not available in
+@samp{GCC}. However, @samp{attributes} are available, and they provide
+virtually identical functionality. For compatibility with other
+AmigaOS @samp{C} compilers, preprocessor symbols are provided, which
+expand to the appropriate @samp{attributes} (@pxref{Attributes}).
+
+@table @samp
+@item __chip
+@xref{chip}.

+@item __saveds
+@xref{saveds}.
+
+@item __interrupt

+@xref{stackext}.
+
+@item __regargs
+@xref{regparm}.
+
+@item __stdargs
+@xref{stkparm}.
+
+@item __aligned
+This expands to the standard @samp{GCC}
+@samp{__attribute__((aligned(4)))}.
+@end table
+
+@quotation
+@emph{Note}: With @samp{SAS/C}, these keywords may be specified either
+before or after the type, so the following declaration is correct:
+
+@example
+__saveds void func(void);
+@end example
+
+Unfortunately, the syntax rules of @samp{GCC} 2.7.2.1 do not allow to
+specify the attributes before the type, so the above example must be
+changed to:
+
+@example
+void __saveds func(void);
+@end example
+
+This will be fixed in @samp{GCC} 2.8.0.

+@node Miscellaneous, Index, Defines, Top
+@chapter Miscellaneous
+@cindex Miscellaneous
+@cindex Uncategorizable
+
+The following ``hard to categorize'' features are available in the
+AmigaOS port of @samp{GCC}:
+
+@menu
+* Explicit register specification:: Specify registers for arguments.
+* Case sensitive CPP::              <String.h> is not the same as <string.h>
+* Library flavors::                 Linker libraries.
+@end menu
+
+@node Explicit register specification, Case sensitive CPP, Miscellaneous, Miscellaneous
+@section Explicit register specification
+@cindex Explicit register specification
+@cindex Specify registers for arguments
+
+In certain situations, like writing callback hooks, ``patchers'',
+standard shared libraries, etc., functions have to receive arguments
+in particular registers.
+
+@samp{-mregparm} (@pxref{-mregparm}) is not appropriate in this case,
+since it does not give the programmer enough control on @emph{which}
+registers will be used.
+
+To overcome this problem in the AmigaOS port of @samp{GCC}, explicit
+register specification has been extended to be available for function
+arguments, as well:
+
+@example
+void myhook(struct Hook* hook __asm("a0"), APTR object __asm("a2"),
+            APTR message __asm("a1"))
+@{
+	...
+@}
+@end example
+
+@quotation
+@emph{Note}: This feature is currently not available in @samp{G++}.
+
+Only the @samp{ANSI}-style declarations (prototypes) are supported.
+
+Registers have to be specified both in function declarations
+(prototypes) and definitions (function code).
+@end quotation
+
+This feature was first made available in the @samp{GCC} 2.7.2.1,
+@samp{Geek Gadgets} snapshot @samp{961012}.
+
+@node Case sensitive CPP, Library flavors, Explicit register specification, Miscellaneous
+@section Case sensitive CPP
+@cindex Case sensitive CPP
+@cindex <String.h> is not the same as <string.h>
+
+The preprocessor available in the AmigaOS port of @samp{GCC} is case
+sensitive. This means, that the header names provided in the
+@code{#include} directives have to be correct, including upper and
+lower case letters. This affects only the way the preprocessor works.
+Currently available native AmigaOS file systems are case insensitive.
+
+@quotation
+@emph{Note}: This might seem like a horrible hack and a crazy attempt
+to implement a ``ridiculous'' UNIX feature on Amiga. However, this
+feature has been introduced to terminate the endless @samp{G++}
+problems with a standard @samp{ANSI C} header @file{string.h}: under
+the AmigaOS, a @samp{C++} header @file{String.h} would be included,
+instead.
+@end quotation
+
+@node Library flavors, , Case sensitive CPP, Miscellaneous
+@section Library flavors
+@cindex Library flavors
+@cindex Linker libraries
+
+The AmigaOS port of @samp{GCC} may use different linker libraries
+depending upon the options used while invoking the compiler. These
+libraries reside in subdirectories of the standard locations, such as
+@file{GG:lib/} or, with @samp{GCC} 2.7.2.1,
+@file{GG:lib/gcc-lib/m68k-amigaos/2.7.2.1/}.
+
+If you invoke @code{gcc} with @samp{-v}, you'll see the precise flavor
+of libraries used as a @samp{-fl} option in the @code{ld} invocation.
+Here is a list of the available flavors (and hence the subdirectories
+names):
+
+@itemize @bullet
+@item 
+@file{libb} corresponds to the @ref{-fbaserel} option.
+@item
+@file{libb32} corresponds to the @ref{-fbaserel32} option.
+@item
+@file{libm020} corresponds to the @samp{-m68020} (or higher) options.
+@item
+@file{libm881} corresponds to the @samp{-m68881} option.
+@item
+@file{libnix} corresponds to the @ref{-noixemul} option.
+@end itemize
+
+More than one flavor can be specified simultaneously. For example,
+when both @ref{-fbaserel} and @samp{-m68020} are specified, the
+libraries will be searched in @file{libb/libm020} subdirectory (as
+well as in @file{libb} subdirectory and in the standard location).
